Houthi rebels have banned UK and US ships from passing through the Red Sea, but have granted safe passage to both Russian and Chinese vessels.
This comes as both the UK and US destroyed dozens of military targets last week in Yemen, with the Houthis vowing to extract "unimaginable" revenge.
Muhammed al-Bukhaiti, spokesperson for the Yemeni rebel group, slammed the UK and the US for their role in the war in Gaza.
He stated that all vessels that have no links to Israel will be safe to pass through the region.

Al-Bukhaiti told Russian newspaper Izvestia: "The madness and idiocy of the USA and UK have played against themselves - now their ships will not be able to use one of the key trade arteries in the world.
"The US and UK will need to stop aggression against Yemen, stop the war in the Gaza Strip and ensure the uninterrupted flow of medicine, fuel and food.
"Only then will we immediately stop all our operations in the Red Sea.
"The war we are waging today is one of a kind in terms of its moral and ethical frontier.

"The whole world sympathises with Yemen's heroic stand to end the genocide of the Palestinian people.
"As for all other countries, including Russia and China, their shipping in the region is not threatened.
"Moreover, we are ready to ensure the safety of the passage of their ships in the Red Sea, because free navigation plays a significant role for our country."
A spokesperson for the Chinese foreign ministry has said that the "harassment" of vessels in the Red Sea must stop.
Mao Ning said: "We call for an end to the harassment of civilian vessels, in order to maintain the smooth flow of global production and supply chains and the international trade order."
Russian Foreign Minister Sergei Lavrov on the other hand called on the US to halt its strikes against the Houthis and instead take a diplomatic approach.
He said: "The most important thing now is to stop the aggression against Yemen.
"The more the Americans and the British bomb, the less willing the Houthis are to talk."
